Relative compression testing using the USB Autoscope

How to perform a relative compression test with the USB Autoscope IV. In this video is shown how to do a relative compression measuring between the cylinders of gasoline and diesel engines. Test ElPower automatically analyzes battery voltage and current waveforms in order to obtain a fast and comprehensive diagnostic of battery, alternator, starter, and other powerful electrical consumers.
To measure relative compression, you should block the engine start for 3...5 seconds during cranking by turning off the engine control system fuse. It is recommended to use the remote fuse switch.

Tools used:
USB Autoscope IV, an 8-channel scope:
